after oxygenation. The first is that the cause of fish floating head is not lack of oxygen, if there are many fish, one or two floating head, the other normal, then this is the case. The second is that the effect of oxygenation is not ideal, or the time is relatively short, the dissolved oxygen in the water does not rise, so the fish's breathing is still blocked, and it will still float.
for the floating head of fish? 1. Water quality problems: The floating head of fish is likely to be caused by poor water quality, indicating that no attention has been paid to changing water at ordinary times. Usually once a week, each time to change about a quarter, not more than one third of the total amount of water, if the water is changed too frequently, or too much at one time, it will be harmful to the health of fish.
2. Ammonia nitrogen poisoning: If you feed too much at ordinary times, the filtration system is not good, and there are too many residual baits and feces in the water, a large amount of ammonia nitrogen will be produced after decomposition, which will lead to fish poisoning and floating head symptoms. In view of this situation, besides properly controlling the amount of food, we should also pay attention to cleaning the bottom of the jar when changing water.
3. Gill disease: When the gills are infected by parasites or bacteria, it can also cause the fish to float, because it affects the fish's breathing. If you want to treat it, you need to use some bactericidal or worming drugs.
